Select which lines to include by the Hours, Arcs, Other and Shadow-caster menus:
o Hours
* Subdivision | Draw the dotted half-hour, quarter-hour or 10-minute lines |
* Hour lines | Draw straight hour lines (the readings will need to be adjusted by the equation of time), shown in black |
* Restriction | Limit the layout of the hour lines to the useful length, which depends on the shape of the shadow-caster |
* S January-June | Draw the curved hour lines for the period from December 21/22 to June 20/21, shown in blue |
* Z July-December | Draw the curved hour lines for the period from June 20/21 to December 21/22, shown in red |
o Arcs

* Date | Draw the arc for the date specified in the input box in the Other tab |
* January-June | Draw an arc for the first day of the months from January to June. These are shown in blue and the dotted arc corresponds to January 1 |
* July-December | Draw an arc for the first day of the months July to December. These are shown in red and the dotted arc corresponds to July 1 |
o Other
* 2 points | Show the position of the 2 shadow points used to perform the calculations |
* Axes | Draw the axis system |
* Squares | Display a grid of square boxes to make it easier to transfer curved lines on to the sundial. The Other tab of the input box allows you to choose the size of the squares |
* Horizon | Draw the horizon line |
* Refraction | Integrate the adjustment for refraction in the layout of curves. This is only possible if you have provided complete location information in the Place tab (latitude plus either half-day or longitude and time zone) |
* Shadow | Show the shadow of the style or the gnomon and enable its animation. If you have provided complete location information in the Place tab (latitude plus either half-day or longitude and time zone) the shadow is drawn according to the refraction effect |
* Desktop sundial | Run the "Desktop sundial" mode. |
o Shadow-caster
* Visible | Display the shadow-caster, which will be represented lying on the sundial |
* Type | Show the shadow-caster as style (triangle or trapezoid) or gnomon (single perpendicular bar) |
